Spoiler!
Ye does not know that it's not his child ....Ye and Gan rui came to agreement that they will convince the child through IVF .
And one more thing those Jiran's parents are not Jiran's biological parents . he was a victim of child trificing and present parents bought him ....and obviously he is not Ji ran his real name is Yun Yi. His real family is realllllllyyyyyy powerful. That's why Ye will have to suffer to get back with ranran.
